The mini 10 V (aka Inspiron 1011) has socketed RAM, not soldered - it can be upgraded to 2G. You CANNOT however use 4G - the Atom processor has the memory controller onboard the CPU, and supports a max of 2G. It's soldered to the board, so the CPU cannot be upgraded.

Getting to the memory is not trivial though - it requires removing the system board:
